Liverpool boss Rafa Benitez is hopeful that central defender Daniel Agger will return to action in a couple of weeks, after suffering a setback in his recovery from a foot injury.
The 23-year-old Denmark international has not featured for the Reds since mid-September, but was close to a return before suffering renewed problems during training last week.
Benitez said: "We are disappointed with what has happened to Daniel Agger. We felt he was ready.
"But when he was training last weekend he felt something when he was tackling. It was right at the end of the session, it was not serious, but enough to cause us concern.
"We have talked to specialists to try to find an answer, but he is now working hard again with the medical staff.
"He had been training well for two weeks, then he just had a little bit of bad luck and he is out again. Maybe it will be two weeks before he is ready again."
Agger joined the Reds two years ago from Brondby and has scored four times in 53 appearances for the Merseysiders.
